DOOR DEVICE.

Specification of Letters Patent. Pdtentgd JguL 24, 1922.

Application filed March 30, 1921. Serial No. 456,896.

To all whom t may concern.'

Be it known that LARTHUR ROBERT RYAN, a subjectof the King of GreatBritain, and resident of the cit of Calgary, in the Province of Alberta,lgominion rofl Canada, have invented certain new and useful Improvementsin Door Devices, of which the following is a specification.

This invention relates to a door device, and the objects ot theinvention are to provide a device which will open and close Adouble 0rsingle doors atthe same time, also holding doors apart when open, thuspreventing the doors from blowing closed.

Other objects are to provide a means whereby the mechanism to lock thedoor can be easily operated, and further objects are toprovide a devicethat is simple in construction and not liable to go out of repair, andgenerally to adapt the several parts to better perform the functionsrequired ot' them.

With the above and other objects in View, the invention consistsessentially of the improved construction particularly described and setforth in the following specification and accompanying drawings formingpart of the same.

In the drawings:

Figure 1 is a vertical section through a door embodying my invention.

Figure 2 is a plan view of a pair of double doors designed t-o openoutwardly and embodying my improved device.

Figure 3 is a perspective view of the car.

Figure 4 is an enlarged sectional view of the door lintel with the railand improved device connected thereto.

'e Figure 5 is a cross section taken on the line 4 4 of Figure 4.

Figure 6 is a longitudinal section taken on the line 5-5 of Figure 5.

Figure 7 is a plan view of a pair of double doors adapted to open inwarly and provided with the improved locking means.

Like characters of reference refer to like Y parts in the severalfigures.

Referring to the drawings, A represents a pair of double doors, and Bthe door lintel, and C indicates the ceiling of the car..

An iron track 10 is carried by the underside of the door lintel B, andextends parallel to the ceiling and is supported at the outer end withan adjustable strap iron brace 11 carried by the ceiling.

A car D is designed. to run on the track 10 and consists essentially oftwo plates 12 and 13 connected by pins 14 carrying rollers 15 designedto engage the side faces of the rail 10.

The top plate 12 is provided with two 4projections 16, the purpose otwhich will be made clear hereafter.

The car D also carries on either side of the rail 10,the upwardly turnedend of two iron bars 17 and 18 extending angularly and connected toprojecting lugs 19 and 20 carried by the top part of the doors A.

The rail 10 is provided at one end adjacent the door lintel B with aclamp 21 pivotally carrying a latch member 22 having a notch 23 thereindesigned to engage one of the projections 16 on the car D when the sameis moved in proximity tothe said latch.

The outer end of the tracklO adjacent the brace 11 is also provided'witha clamp 24 carrying a latch member 25 and notch 26 also designed toengage one of the projections 16 provided on the top plate 12 of the carD.

Each of the latches 22 and 25 are provided on the top face thereof witha ring 27 through which a rope or wire 28 passes.

The rope or wire 28 is fastened at one end to the adjustable brace 11and extending parallel to the rail 10 through the rings 27 engages aneye 29 carried by the door lintel B and extends downwardly and has itsextremity provided with a handle 3() by the handling of which thelatches 22 and 25 may be worked.

When in use and if the doors are closed as shown in Figure 4, the latch25 will be in engagement with the prfgection 16 on top of the plate 12of the car and should it be desired to open the doors A, the rope 28 ispulled downwardly so as to disengage the latch 25 from the projection 16when the doors will open, on slight pressure being applied against them.

As soon as the car D travelling on the rail 10 passes under the latch22, the hold on the rope 28 is released and the latch 22 will be loweredand thus caused to engage the second projection 16 on top of the carthereby locking the doors in open position.

It will be seen that the device can be adapted to double swinging doors,when the car and latches 18 and 17 will take the position shown inFigure 2 in dotted lines. lVhereas they will adopt the position shownlin dotted lines in Figure 7 when they fare swung inwardly. e

The device 1s herewith shown connected to a barndoor, but it will beunderstood vthat the same can be suitably worked in connee tion with anydoor and even with a single door.

The clamping` members 2l and 2l may be slidably mounted on the rail andprovided on the underside with a thumb screw 31 by means of which it canbe fastened in position on I'the rail. It will be seen by this means thedoors can he opened to the desired 'degree and locked in that position,

lVhen-the doors are adapted to swing outwardly and inwardly, the lugs 19and 2O are made to extend higher than the ldoor so as to allow the samelfree passage under the rods l? and'lS when the doors are open inwardlyas shown in dotted lines in Figure 7.

As Vmany changes could be made in the above construction, and manyapparently Widely dierent embodiments of my invention, within lthe scopeof :the claims', constructed Vwithout departing from the spirit orscopethereof, it is intended that-all mat'- ter contained .in theYaccompanying specifi- 'cation and drawings shall be interpreted asillustrative and not in a limiting sense. Vhat I clalm as my invention1s:-

l. door locking device comprising in combination with a door, a railhaving one end :fastened Yto 4the door Il intel, a bracey supporting theopposite end of the rail, a car in slidable engagement with the rail andcomprising a top plate, a lower plate, pinsA holding the plates aboveandV beneaththe rail, rollers on the pins designed to engage the rail, arod onthe doorhaving one end brace,l an eye on the door lintel designedto engage the downwardly extending endnofthe wire, and a hand grip onthe end of the wire. In witness whereof I have hereunto set my hand inthe presence of two witnesses.
